TATA Motors NEXON EV, Owner'S Manual

Page: 13 / 232

HIGH VOLTAGE BATTERY SYSTEM
Nexon EV is powered by a lithium ion bat-
tery pack and it is managed by a highly in-
telligent battery management system that
controls the output and behavior of the
high voltage battery pack. This BMS is
powered up by the low voltage battery
present in the vehicle.
It is essential to ensure the presence of
ample voltage in the low voltage battery to
enable the function of the lithium ion bat-
tery. Please refer to the LV battery main-
tenance section to maintain your battery at
optimal working conditions.
It is essential to note that even when the
Nexon EV is not in use, the HV battery un-
dergoes discharge (Approx. 2% State of
Charge in 30 days) over a stagnant period.
Hence, to optimize the life of the battery,
please ensure the vehicle is plugged into
the charger so as to maintain the required
level of charge.
The HV battery must never be allowed to
discharge completely, as this situation
causes a damage to the life of the battery
and must be charged regularly.
In a situation where the vehicle has under-
gone complete discharge, please contact
the TATA MOTORS EV service centre for
further assistance.
It is recommended to charge up to 100%
during every charging for best perform-
ance of battery pack.
If warning related to battery appears, com-
municate to TATA MOTORS EV service
center.
The Nexon EV is powered by a 30.2kWh
high voltage lithium ion battery pack,
which in turn powers the electric motor to
drive the front wheels. This high voltage
battery also powers the air-conditioner,
and an auxiliary battery (12 V) that drives
the lamps, wipers, and audio system. The
auxiliary battery is automatically charged
when the vehicle is in the ready mode or
the high voltage battery is being charged.
Before you drive the car, it is essential that
you read the owner’s manual to under-
stand the basics of battery and charging of
your EV to prolong the life of battery pack.
Be sure to read the warnings and cautions
in the following sections.
Since the battery pack is not user service-
able, we urge you to visit the nearest Tata
Motors authorised EV service centre to
safely recycle or dispose the battery. Do
not attempt to recycle or dispose the bat-
tery yourself, as it might result in severe
WARNING
The battery and motor are not user
serviceable. Do not inspect, remove or
disassemble any of the high voltage
electrical components in your vehicle as
it could cause severe burns or even
death.
